INTERCHANGEABLE ELECTRIC SIGN;

Application. ri ed .a rn 11," 1924., Serial No. 205,912.

o aZZ whom, it may concern.- 1 Be it known that I, Mnnvrn l'lAAKlENSON, a citizen of the United States, residing'at VVestby, in the county of Vernon and titate of iVisc-onsin, have inventedcertain new-and useful improvements in Interchangeable Electric Signs, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to interchangeable electric signs, and the object of the invention is the construction of a simple and efiicient electric sign which can be easily placed on exhibition and which is of such a structure as will be very efiicient for exhibition p'nroses. p Another object ofthe invention is the improvement of the construction of the, signs that are placed in the device, as well-as the improvement of the spring clip devices for holding the signs securely nd efliciently in position upon the hinged cover. I

With the foregoing and other objects in view, my invention comprises certain novel combinations, constructions and arrange ments of parts as will be hereinafter described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims. v

In the drawings:

Figure l is a perspective View of a device constructed in accordance'with the present invention.

Figure 2 is a sectional view taken on line 22, Fig. l, and looking in the direction of the arrows.

Figure 3 is an enlarged, sectional View of the cover with one of the signs in place thereon.

Figure 4 is an enlarged, fragmentary, perspective view of the cover, showing particularly the fastening device.

Figure 5 is a sectional View, taken on line 5-5, Fig. 4:, and looking in the direction of the arrows.

Figure 6 is an enlarged, fragmentary, perspective view of the cover frame.

Figure 7 is a perspective view of the spring clip.

Figure 8 is a fragmentary, perspective view of one of the signs, looking at the front of the same, whereas Figure 9 is a fragmentary, perspective view of one of the signs, looking at the rear face thereof.

The sign 8 can be made to expose different words and different characters-thereon but their general structure includes a front card board 9, with strips ofcol-ored material 10. cover ng apertures 11, which apertures ll may be of a decorativetype, at the will of.

improved sign, being somewhat thick,"while not decreasing its efiiciency, produces a cushioning effect when clamping it infp'lace upon the cover 5. v

To hold the sign 8 against the glass 7, I provide two fastening devices upon the cover, and as they are similarly constructed it will only be necessary to describe one.

' Each fastening device is formed by cutting a socket 124 in the cover, then cutting a groove 15 in the face of the socket; this groove has a high point? 16 at its middle so that the inwardly-extending tit 17011" the spring clip 18 will ride up onto'this high point 16, as shown in Fig. 5, causing a greater clamping action of thevspring clip against the sign 8, pressing'in onth'e sign,v

' holding said sign snugly in position, as

clearly shown in Figs. 3 and 5. lhe spring clip is pivotally mounted upon the fastening means 19, and while it is of an eflicient structure, it can be easily operated for allowing different signs to be placed in position upon the cover.

I provide a fastening device 20 for holding the hinge-d cover 3 in a closed position upon the container 2. v

The entire apparatus can be placed in any desired position for exhibition purposes, as it is especially adapted for use ina display window, or on a counter, or the like. v

manufacture of the same and I, therefore,

' reserve the right to make such alterations or changes as shall fairly fall within the scope of the appended claims. I

' What I claim is: v 1 In a structure, of the within'the recess anarcuate groove increasing in depth towards its ends whereby a high point is formed intermediate its ends, and a spring'clip pivotally mounted in said socket and having one end portion extending from thesocket and adapted to press upon a sheet carried by the frame, the inner end portion of the clip being provided with a tit traveling in said groove whereby the T clip may be tilted to exert its maximum pressure upon the "sheet when the tit is on the high point of'the groove.

2. 1m a structure of thecla'ss described, a sign carrying body provided with fastening devices for'holding, the sign in position, each fastening device including a socket having a groove, therein, said groove being shallovs at its middle producing a high point, and

' a' spring clip movable in said socket and pro- Wided with means travelling in the groove and adapted to engage said high point certain minor changes or alterations.

, class described, a frame having a socket provided therein and for causing onend" of the springlclip-to press firmly upon a sign placed against the body, substantially as shown and described; I,

3. Ina structure of the class described, a sign carrying body, a sign against said body, spring clips pivotally mounted on said body and bearing against said sign, the body being provided with cam surfaces beneath the clips, the spring clips provided with means for engaging the cam surfaces and fitting the clips to cause the clips to exert a'greater amount of pressure on the ,sign when the clip is extending furthest over the sign.

4. In a structure of the class described, an open frame provided with a glass're'ceiving portion, a glass in saidreceiving portion, said frame provided on opposite sides and contiguous 'to'the glass with sockets and in each of. said sockets with an arcuate' groove, said groove, having its ends opening upon. the glass and increasing in depth from its intermediatepoint towards its ends, a sign against said glass, a. spring clip in each socket, fmeans pivotally fastening said clip in said socket, and said spring clip provided with as depending tit travelling in said groove and adapted to engage the shallow intermediate portion of the groove. when the clip'is extending furthest over-the sign,

substantially as showniand described.

In testimony whereof I hereunto'afiix my signature. 9
